Is Space Mining Feasible?
There is a large amount of precious minerals on the Moon and Mars. Would it be feasible to bring these valuable materials back on Earth? Space.com says that mining specialists and space engineers, who gathered at the latest Space Resources Roundtable, think the answer is yes.

But there are many issues to solve. The first one is to build a permanent base. Then, you have to live on space resources.

If humans are ever to truly spread their wings in space, they must be nourished and sustained by space resources. That means no less than "living off the land", severing the supply umbilical of Mother Earth. It's also tagged as in-situ resource utilization -- or ISRU in space lingo short speak. Off-world resources can be transformed into oxygen, propellant, water, as well as used for construction purposes and to energize power stations.

"ISRU really is the stepping stone, a key part of the development of space," said Gerald Sanders, Chief, Propulsion and Fluid Systems Branch at NASA's Johnson Space Center in Houston, Texas. "We can do things at low Earth orbit bringing materials up from Earth. But once you start getting any distance away from low Earth orbit, the leveraging just isn't there," he told SPACE.com .
The article looks at other issues, such as strategic and economic potentials, before examining legal concerns.

The greatest need -- to prepare not only for Moon mining, but also digging out resources from Mars -- is not for technological breakthroughs. Rather, it is for information and clarification.

That's the belief of Leslie Gertsch, Assistant Professor of Geological Engineering at the Rock Mechanics & Explosives Research Center at the University of Missouri-Rolla.

It is obvious that fundamental differences exist between the working conditions on Earth contrasted to the Moon and Mars, Gertsch said.
First of all, Gertsch said, the legal landscape for extraterrestrial resource ownership and extraction must be clarified. Additionally, there needs to be detailed feedstock specifications for products that could be made using off-Earth materials. Obtaining more, and higher resolution data on prospective deposits needed for space mining -- using both orbiters and landers -- is critical too. Lastly, achieving and maintaining the link to the Moon and Mars is key, she said.

So, we'll need lawyers for space mining. As the article says, it "turns out you can't leave Earth without them."

If we do this, we might be doomed when we accidently destroy the moon. Ever see The Time Machine? :eek:
 
I don't think the moon is a going to be a mining project. It would not be nice to mess with it's gravitational relationship with earth. Mars, I believe, and asteroids are the subjects of study right now.

Codger, naw, I believe they will mine the moon first before they can do anything... since Moon have the highest concentration of D Helium 3. Without D Helium-3, it is nearly virtually impossible for anyone to space travel.
 
This is all I could find on D H3 on the moon. Space travel can't take place without it? Haven't heard that before.

The possibility that helium-3 may be widely found on the Moon has led to discussions (http://slashdot.org/article.pl?sid=04/11/27/1931205&from=rss) as to whether it could be used as an energy source. The big downsides to helium-3 are that the ignition temperature is ten times higher than convention fusion, and thus considerably harder to fuse. Breakeven has not been achieved with conventional fusion. Helium-3 fusion is thus only a potential power source, rather than one likely to be useful in the midterm. In addition, the quantity of helium-3 that gets trapped from the solar wind in the lunar surface has never been determined, and may be below the economic mining point.

I read several books on space travel sometimes ago, I learned about D Helium-3 and nuclear fusion. It is very, very effective fuel for space travel.

One of japanese books mentioned that Moon have the highest concentration of D Helium-3 but not enough quantity to support the space 'airport' so they cannot build the space 'airport' on Moon for space travel (reduce the gravity pressure on the spaceships when depart from the planetside). Jupiter, I believe have the massive quantity of D Helium-3.

Edit: There is an alternative fuel to resolve some D Helium-3 problems -- Hydrogen if need.
